Motion compensating crane for moving cargo containers at sea - GIF

[PJs]

It's articulate and speaks well for Enginerdingness! Pretty Kool mechanisms. Looks like a dock to ship system in the end but in beginning as the crane appears dynamic first 7 seconds (camera 1) and not in later 7sec of frames (camera 2). Even though it's sped up the cable drives on the jib and Z axis must be some kind of Laser guided control system, maybe a fluid balancing system to be agile enough especially if both units are moving. Would like to know more, as it doesn't look like a hoax, but an odd compilation.

Where did you find this Jon?
